Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed August 28, 1917. Serial No. 188,613.

To all whom it may concern:

Be it known that I, ALFRED D. CREssLER, a citizen of the United States,residing at lvashington, District of Columbia, have invented certain newand useful Improvements in Apparatus for Charging and DischargingGas-Retorts, Slots, and Chamber- Ovens, of which the following is aspecification.

My invention relates to an improved and novel apparatus for charging anddischarging gas retorts, slots, and chamber ovens, in the manufacture ofcoal-gas, coke and byproducts.

The main object of this invention isto provide simple, strong, durable,economical, novel and thoroughly efficient devices for the charging anddischarging of gas retorts, chamber ovens, slots and the like, whenpositioned horizontally or in an inclined position, said charging beingperformed simultaneously with the act of discharging, and the saidretorts are charged and discharged in series.

A further object of the invention is to furnish means whereby therespective bench capacity is increased by filling substantially theentire area of each retort during the charging operation.

A further object of the invention is to furnish means whereby therespective bench capacity is regulated by charging each series ofretorts with a predetermined quantity or weight of coal, uniform andlevel throughout the full length of each retort between the insidesurfaces of the front and rear arch walls.

Another novel object of mydnventionis to increase the carbonizingcapacity of each gas bench of a predetermined area over present standardcarbonization methods by charging each retort with coal to substantiallyits full area by means of an equalizing and charge regulating core andplunger and pusher, which conveys the coal and pusher from a series of.magazines into the retorts and by reversing the action of the plunger,the core is withdrawn from the retort, causing the coal to settle fromthe top providing ample area in each retort for outlet of gas andexpansion. of the coal during the process of carbonization, the chargeof fresh coal being delivered, each r t rt f th Series,

en massc, in one continuous uninterrupted operation and simultaneouslywith the discharge of coke.

Another object is to provide improved and novel devices which may beeasily and readily manipulated by a minimum amount of labor, therebyconstituting both a time and labor saving medium.

Another object of the invention is to furnish means whereby the act ofcharging and discharging of the retorts is performed in series and atthe same time the charge-in each retort is regulated to meet therequired conditions.

A further object of the invention is to couple each series of retortswith a single stand-pipe, also hydraulic mains on both front and rear ofthe bench of retorts or chamber ovens, and so arranged that the richgases passing off during the early hours of carbonization are dischargedthrough the stand-pipe at one end of each series of re torts and thelean gas made and passing off the last hours of carbonization and duringthe time the charge is held in the retorts to harden the coke isconveyed through the stand-pipes at the opposite end of the series ofretorts, the hydraulic main being connected with a separate exhausted,condensing, washing and stripping apparatus; also a storage holder.

Another novel object is to provide charging means for maintaining thecoal in each retort in such position as to receive the full force of theheat of the furnace throughout the entire length of the retort duringthe period of carbonization.

Another object of the invention is to so construct my improved devicesthat all gases generated will be saved during the process of 'chargingand discharging each series of retorts. 7

A still further object of this invention is to provide a novel magazinepharging device arranged in series or singly, each magazine "beingfilled or charged witherushed coal while in a vertical position, thentilted to the proper discharging position and the seriesof magazinesmanipulated to enter the cast-iron mouth-piece of the series of retorts,in combinationxwith automatically operated means for discharging enmasse the contents o the Series of azines ithin the e i s of retorts,and simultaneously discharging the coke from and cleansing the innersurfaces of each retort of the-series.

Another object of this invention is to provide a novel and simplehorizontal coalcarrying and charge regulating core, fixed insideeachmagazine, with a portable discharging device on the forward end, and aportable charge pusher in the rear, whereby the hot coke is dischargedand the fresh charge of coal delivered into the series of retorts orchambers Without coming into contact with the coke, thereby preventingthe making and wasting of gasduring the procass of discharging andcharging the retorts or ovens,

Another useful and novel object of my invention is in the use ofperforated steel disks, for the ends of the portable discharging deviceand eachpushing device, allowing a free passage of the gas at either endof the retorts to the stand-pipe. One disk on each pusher is also fittedwith an adjustable scraping and shaving device fitting against thevinside surface of the retorts during the operation of each charge anddischarge, and made of any suitable material, thereby pre venting theaccumulation of carbon in the retorts. 1

Another novel object of this invention is to adjust only the front endof the steel magazine charging device the distance of the cast-ironmouth-piece and not its full length, into the inside of the retorts,during the process of discharging the hot coke and charging the freshcoal, thereby preventing damage, or destruction of the steel magazine.

Still another object is to provide a device for simultaneously fillingthe series of magazines with coal while in a vertical position directfrom overhead charging hopper tubes, thentilting the series of magazinesto a suitable discharging position to deliver the charge into the seriesof retorts, the discharging device being inserted into the front end ofeach magazine preventing the spilling of coal during the operation ofdischarging or charging the retorts or ovens during the conveying of,the series of magazines from the coal charging hopper tubes. WVhen theretorts are charged with fresh coal the end of the magazinesextendinginto the cast iron mouthpiece and the solid disk forming thefront of the portable discharge pushers effectively close the ends ofthe retorts thus preventing .the' first made rich gases from escapinginto the atmosphere, but forcing such gases to be conveyed to thehydraulic main through the rear stand pipes, thereby increasing both thequantity and quality of the gas made and preventing the escape ofthevapors into the air.

The foregoing and such-other objects as may appear from the ensuingdescriptionare attained by the novelfeatrdes of construction,combination, location and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings and particularlypointed out in the claims appended hereto, it being understood thatslight changes in the form, proportions and minor details of theconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In carrying out this invention as illustrated and which shows apreferred construction, the numeral 1 indicates the front wall and 1 therear Wall. of a coal gas oven, said oven being provided with a bench ofnine horizontally arranged retorts or chambers 2, arranged in seriesconsisting of three retorts or chambers to each series, each seriesbeing connected or coupled with a single upright stand-pipe or ofi'take3 for conveying the to the hydraulic mains 4:, at each end of the benchor stack of retorts, and being-so arranged that the rich gases arecarried away through the stand-pipe at one end of each series ofretorts'or chambers, and the lean gas is conveyed away by the standpipeat the opposite end of each seriesof retorts or chambers, as clearlyshown in Fig. 1 of the drawings. While I have shown a bench of nineretorts or chambers arranged in series of three each coupled together invertical alinement, each of the series of retorts being charged anddischarged simul taneously, it will be understood that any suitable ordesirable number of, retorts or chambers may be utilized, and anysuitable number of the retorts may be coupled inseries or arrangedsingly for simultaneous charging and discharging, and if desired theretorts or chambers may be arranged in an inclined position instead ofthe horizontal position as shown. j V 7 Each of the retorts or chambersis provided at one end with a mouth-piece or-en- 'trance-n iember 5provided with a'gas discharge opening 6 leading to the off-takeorstand-pipe, and at the other end with a-discharge or exit member 7,having a gas discharge opening 8 leading to the off-take 3, each retortor chamber being suitably supported in the gas oven, and provided ateach end with any well-known construction of coveror lid. 1 '1 fArranged parallel with the bench of retort/S or chambers at theirentrance ends, and

movably supported on track rails supported by the flooring or a suitableplatform, is a portable magazine charging and discharging carriage,comprising a truck member or frame 9, supported by wheels 10 said framehaving secured thereto two upright transversely arranged members 11.,each member having a centrally arranged recess in the upper longitudinalsurface in which is secured a rail 12, adapted to slidably support apivoted or swinging frame 13, provided with a member 14 at each sidethereof adapted to be slidably supported on the rail 12. Suitably andrigidly secured in a horizontal position .to said frame 13 in verticalalinement, is a suitable series of coal carrying magazines 14 andcentrally secured to the frame 13, at each side thereof, is a lateralextension 15 adapted to form a bearing socket for the frame pivotalpintles or stub shafts 16, which rest within and project be yond thesaid sockets. Suitably secured to one side of the frame 13 is a metallicplate 17, having a notch 18 formed in its peripheral portion adapted toreceive and engage the locking member 19, carried by the hand lever 20secured to the pivot pintle or shaft. 16, and adapted to lock the seriesof magazines when tilted by the said lever into the vertical position,as shown by dotted lines Fig. 2.

Rigidly secured to the frame 9, are two upright brackets, in which issupported a tubular sleeve 22, provided with an internal.

screw-threaded end portion 22 adapted to engage with a screw-threadedrod 23, which is secured at one end to a bar-.24, the latter beingpivotally secured to an upright lever bar 25, pivotally secured at itslower end to the frame 9, and at its upper end to a horizontallyextended bar 26 secured to the pintle or shaft 16, and suitably securedto the frame 9 is a metallic upright member 27, provided with an opening28 adapted to receive and support shaft 29 provided at one end with abevel gear-wheel 30 engaging with a bevel gear wheel 30 supported by thebracket 21, the other end of said shaft 29 being J provided with anoperating handle 29, as shown in Figs. 2 and 3, which handle whenmanipulated to the right or left causes the frame with its series ofmagazines to slidingly advance and the in agazines to enter themouth-pieces of the series of retorts for the charging and dischargingoperation or to slidingly move away, respectively, and be disengagedfrom the retorts for the purpose of moving the magazine carriage" intothe proper position for. another charge;

The magazines are each provided with a metallic equalizing or regulatingcore bar 31 for properly and suitably regulating the charge to be forcedinto the retorts or chambers, said core-bar consisting-of a horizontalmember 32 and a central depend g member 33, and being provided at itsouter end portion with an integral disk 34 adapted to snugly fit theinterior surface of the magazine wall and close its outer end, whichdisk has rigidly secured thereto or integral therewith at its centralportion an outwardly projecting annular solid metallic member 35, whichpasses through an opening 35 formed in the inner end wall of themagazine, said member 35 having an annular notch 36 formed therein, anda cone-shaped outer end 37 for the purpose hereinafter described.Projecting outwardly from the peripheral portion of said disk 34 is amember 38 adaptcd to engage a recessed or slotted portion 39 formed inthe inner end wall 39 of the magazine which serves to prevent any rotarymovement of the said core-bar, and each magazine is provided with aninwardly 'ex tending longitudinal metallic guide plate 40, suitablysecured thereto, which plate 40 is straddled by the plates 41, onesecured to each side of the central member 33 of the core-bar, therebyserving as a true guide for the core-bar in its reciprocating back andforth movement during the charging and discharging operation of theretorts and its withdrawal and preventing any wabbling or sidewisemovement of said corebar.

A core-bar is normally secured in eachmagazine and when it is desired tofill the magazine a charge pusher is passed over the outer end portionand caused to assume a position against the disk 34, as shown in Fig. 4and by dotted lines Fig. 8, said charge pusher comprising two perforatedmetallic plates' 42, each provided with a horizontal slot 43, and avertical slot 44, so that the pusher may be slid over the corebar to therear end-portion thereof, said plates being provided with a series ofopenings or perforations 45 therethrough to permit the escape of gas,and being secured at a suitable distance apart by suitable threadedbolts 46, and nuts 47, as clearly shown in Figs. 10 and .11. have beenproperly filled with the measured charge of coal, a portabledischarge'pusher consisting of two metallic plates 42 and 43 is insertedin the front end of each magazine in contact with the core bar and coal,said platesbeing connected together with suitable bolts and'nuts such asare used in connection with the charge pusher hereinbefore described,the rear plate 42' being provided with suitable openings or perforationsfor the escape of gas therethrough, and having a vertical slot 44, 'topermit the discharge pusher to be slid over the reduced front endportion 31 of the core-bar, as shown in Fig.

-4, and the said rear plate 42 is provided with a plurality ofadjustable scraping blades 45, each blade having an elongated slot 46therethrough adapted to receive a suitableadjusting device 47, asshownin After each ma azine of the series shall" Fig. 16, whereby thesaid blades may be so adjusted as to scrape and clean the inner surfaceor wall of the retort as the discharge pusher is forced from the frontto the rear thereof, while the front plate of the discharge pusher ismade of a solid plate or disk 43. Thus the front plate and scrapingblades serve to push out the coke, and clear the gas retort or chambersimultaneously with the charging of the retorts or chambers with a freshsupply of coal.

Arranged parallel with and at one side of the magazine carriage, is aportable motor carriage supported on rails secured to the flooring or asuitable platform, said motor carriage comprising a frame 48, supportedon wheels 49, and said frame supporting a series of cylinders 50, eachcylinder being provided with a reciprocating plunger 51, and eachplunger having secured to its forward end a spring-operated pivotedlever 52 provided with a catch or latch 53, adapted to engage theannular notched portion 36 of the member 35 carried by the rear end ofthe core-bar 31, with the end 37 of the member 35 resting within thetubular end portion 54, and against the solid end wall 54 at the outerend portion of each plunger. Suitably connected to the frame 48 at eachside thereof is properly arranged a compressed air supply pipe 53 and anexhaust pipe 54, each supply pipe and exhaust being connected to thesaid cylinders by the manifolds 55 and 56 at each end of the cylinders,a shutoff valve 57 being arranged in each supply pipe, and a valve 57 ineach exhaust pipe, each valve being provided with an arm 58, to whicharm is pivotally connected a bar 59 to which bar is secured an operatinglever 60, the precise construction and arrangement of the parts beingthe same at each side of the carriage and by the proper manipulation ofsaid lever the air supply to the cylinders is controlled and the seriesof reciprocating plungers moved into proper alinementwith the filled orcharged magazines and coupled with the outer end of each core-bar, theouter solid end portion of each plunger engaging with the cone-shapedprojecting portion of said core-bar and the plungers automaticallyprojected forward, thereby discharging the series of filled magazinesinto the series of retorts and simultaneously discharging and cleaningout the series of retorts or chambers, after which the withdrawal orreturn movement of the series of plungers simultaneously withdraws andreturns each core-bar to its normal position within each magazine tocontinue the oharging and discharging operation, as is clearly shown inFigs. 4 and 5 of the drawings.

Referring to Fig. 7 will be seen a storage bin or bunker 61 having ahopper-shaped bottom portion 62, provided with a series of dependingdischarge tubes 63, Which tubes mouth-piece of the retort.

are adapted to measure and discharge into the magazines supported on themagazine carriage and arranged in vertical alinement with said dischargetubes, a suitable and predetermined quantity of coal to constitute themost desirable and effective charge for properly filling or chargingeach of the gas retorts or chambers.

It will be seen by reference to Fig. 12 that the mouth-pieceof eachretort is provided with a gravity catch or retaining latch 64 whichserves to prevent the accidental withdrawal of the charge pusher fromthe retort during the withdrawal of the core by the operating plunger51, the disk 34 being provided with a slotted portion 65 which permitsthe core to freely pass the said catch, and the outer end of eachmagazine is provided with a suitable slot 66 to prevent in any mannerthe engagement of the ends of the magazine with the said catch or latch64.

lVhile I prefer to utilize my improved charging, discharging andcleaning apparatus in connection with cylindrical or tubular retorts orchambers, it will be readily obvious that by making slight changes inthe shape or contour of the several members employed the apparatus maybe readily utilized for the charging, discharging and cleaning of anyshape of retort or chamber now in use in the manufacture of coal gas,coke and by-products.

It will be perceived by reference to Figs. 1 and 4, that the chargepusher provided with its perforated end plates is 'so positioned in theretort as to occupy only the space which is surrounded by the front ovenwall 1, while the discharge pusher and cleaner provided with aperforated rear end portion and a solid front portion occupies a spacein the retort surrounded by the rear wall 1 and the discharge or exitmember 7, the entire charge of coal being held intact between the outerend of the charge pusher and the inner end of the discharge pusher insuch position as to subject the full charge of coal to the entire heatof the oven, the end of the magazine being entered into the The gasgenerated from the fresh charge of coal is carried off through the rearstand pipe thus preventing the wasting of the same into the atmosphereas is now customary by the present methods employed, thereby increasingboth the quantity and quality of the gas.

I desire it to be' understood that the charge is equalized and regulatedby the size of the core employed in connection with each chargingmagazine, since a core of predelei-mined dimensions may be utilized soas to fill each retort to its full capacity and at the same time allowfor the expansion of the coal within the retort, and sufficient spacefor the escape of the gases at each end of the retort when the coreiswithdrawn from the loaded retort back into the empty magazine.

Further, it will be understood that any "suitable motive power may beemployed for operating the plungers carried by the portable motOrcarriage, as well as the tilting and slidable frame carried by theportable magazine carriage.

The operation of my improved apparatus briefly described is as followsz-Each of the coal carrying magazines which are pivotally supported andcarried by a movable carriage, contains themovable equalizing and chargeregulating core bar 31, and said carriage is moved to a positiondirectly beneath the coal supply and said magazines tilted to an uprightposition the charge pusher is inserted into each magazine; the magazinesare then properly filled with a measured supply of coal by means of thecoal supply tubes shown in Fig. 7, and a discharge pusher is insertedinto the end of each magazine with its inner end plate in contact withthe coal; the said carriage is then moved into alinement with theretorts to be charged; the magazines being tilted into a horizontalposition they are adjusted inwardly within the mouth-piece of eachretort by the operating mechanism carried by the said carriage until theend of each magazine contacts with the end of each retort, when themotor carriage carrying the operating plungers is moved into properalinement with the magazine carriage, and the outer end portion of eachplunger is connected to the rear extension formed on each of theequalizing and charge regulating cores; the motive power being thenapplied the said plungers will be caused to move forwardly in unisonthereby -causing the discharge pushers, the charges of coal and thecharge pushers to move in unison into the position shown within themiddle retort illustrated in Fig. i of the drawings, whereby the coke inthe retort will be discharged simultaneously with the entrance ofanother charge of fresh coal into the retort; the motive power beingthen reversed the plungers are withdrawn carrying back with them theequalizing and regulating cores into their proper position within themagazine, and leaving the charge of coal within the retort, and thecharge and discharge pushers in the position shown in the bottom retortas illustrated in Fig. 4.
